From 40 Questions About Interpreting the Bible, Robert L. Plummer.
From his chapter discussing the interpretation of historical narrative:
One of the most helpful ways to learn how to interpret historical narrative is to listen to or read numerous examples of judicious interpretation. The wise interpreter is always seeking the authorial meaning of the text and does not use extraneous details for his own sermonizing flights of fancy. Such careful interpretative skill is more often caught than taught. For this reason, it is helpful to read commentaries by skillful interpreters. By reading such commentaries, one will begin to absorb both the artistic touch and the analytic mind that are essential to careful interpretation. The beginning interpreter of narratives is also encouraged to find a wiser, more experienced reader who can offer critique and correction. Such solicited feedback, albeit immediately painful, will in the long run be quite salutary.
